Paragraph 107. The backstitch, as the name implies, is made by setting the needle back on the right side of the material halr the length of the stitch just made on the underside, thus making a continuous line of stitches resembling sewing machine work.
First sew over and over with a small stitch to fasten the thread. Insert the needle where you began the first stitch and take a stitch forward under the cloth the length of two stitches, bring the needle through and insert it where the first stitch ends, bringing it under the cloth the length of the two stitches again. See Figure 8. Repeat, keeping the line straight and the stitches even. Fasten by sewing over the last stitch two or three times.
This is a strong stitch which may be used any place where ma-chine stitching would be desirable or where particularly strong hand-made seams are required.

Paragraph 108. This stitch is a combination of the running stitch and the backstitch. To begin it, sew over a small stitch two or three times, then insert the needle as if to sew over again, without removing the needle, take two short running stitches forward, draw the needle through to the right side. Set the needle back at the beginning of the last stitch, bring it through at the end of that stitch and again take two running stitches on the needle. See Figure 9. Continue this process.
